CssSelector Component
CssSelector converts CSS selectors to XPath expressions.
The component only goal is to convert CSS selectors to their XPath equivalents:
use Symfony\Component\CssSelector\CssSelector;
print CssSelector::toXPath('div.item > h4 > a');
HTML and XML are different
The CssSelector component comes with an HTML extension which is enabled by
default. If you need to use this component with XML documents, you have to
disable this HTML extension. That's because, HTML tag & attribute names
are always lower-cased, but case-sensitive in XML:
// disable `HTML` extension:
CssSelector::disableHtmlExtension();
// re-enable `HTML` extension:
CssSelector::enableHtmlExtension();
When the HTML extension is enabled, tag names are lower-cased, attribute
names are lower-cased, the following extra pseudo-classes are supported:
checked, link, disabled, enabled, selected, invalid, hover,
visited, and the lang() function is also added.
